The cards in this 60-card set measure approximately 1 15/16" by 3 1/4". The 1979 edition of Kellogg's 3-D baseball cards have a 3/16" reduced width from the previous year; a nicely designed curved panel above the picture gives this set a distinctive appearance. The set contains the largest number of cards issued in a Kellogg's set since the 1971 series. Three different press runs produced numerous variations in this set. The first two printings were included in cereal boxes, while the third printing was for the complete set mail-in offer. Forty-seven cards have three variations, while thirteen cards (4, 6, 9, 15, 19, 20, 30, 33, 41, 43, 45, 51, and 54) are unchanged from the second and third printings. The three printings may be distinguished by the placement of the registered symbol by Tony the Tiger and by team logos. In the third printing, four cards (16, 18, 22, 44) show the "P" team logo (no registered symbol), and card numbers 56 and 57 omit the registered symbol by Tony. Cards still found with the wrapper intact are valued 25 percent greater than the values listed below. The set was available from Kellogg's for two boxtops and $2 and the offer was available until April 30, 1980.
